Connectivity requirements

Overview

This page shows the connectivity requirements of every Nexthink product. If you operate in a restricted environment, your network administrator must add the domains on this page to an allowlist.

Some Nexthink products allow you to use a secure or a non-secure channel for specific services. Depending on their configuration, you may need to allow connections through a port number that is different from what is shown here.

Your Nexthink URL pattern can be one of the following:

• <instance>.<region>.nexthink.cloud

• <instance>.data.<region>.nexthink.cloud

URL pattern description:

• <instance> - The name of the Nexthink instance.

• <region> - The name of the localization of the instance:

  • us - United States.

  • eu - European Union.

  • pac - Asia-Pacific region.

  • meta - Middle East, Turkey, and Africa.

Ensure your firewall has TCP port 443 open for your Nexthink instance URL.

The following tables indicate the transport protocol for each connection. When an application protocol handles the connection over the transport layer, the application protocol name precedes the transport protocol name.

Web interface

Telemetry and monitoring

Collector

Also, the Windows Collector calls a Windows API method once every 24 hours. The API method triggers a connection for the client to the domain controller operations through TCP port 135. Service responses use ephemeral TCP ports in the 49152-65535 range.

Data export

Nexthink users can export the results of their investigations using the export function. Each user can perform one export at a time. Multiple users of the same Nexthink instance can run a maximum of five exports in parallel.

The data export generates a link to an export file. This is a pre-signed link to an Amazon Web Services (AWS) S3 bucket, which is valid for 10 minutes. The link uses Amazon virtual-hosted-style. See the following example to understand the link structure.

The following part of the URL is static for each request:

https://aris-export-<region>-884848470805.s3.<region>.amazonaws.com

Add this part to the allowlist of your firewall; change <region> in both places to the region of your tenant.

Data Enricher (classic)

Finder (classic)

Nexthink Finder is a Windows-only desktop application. Its functionality is available within the Nexthink web interface. Nexthink can now be used directly from a browser, and most functions no longer require an additional desktop application.

Engine (classic)

If rule-based Collector assignment is turned on, the TCP channel of Collector also connects to the Nexthink web interface. Collectors use this connection to ask for their assigned Engine (classic). Collector can no longer use a UDP channel to send end-user analytics to the Engine (classic).
